, To all lwho'mfr may concern:

Be it known that I, DANIEL R. ScnoLns, citizen of the- United States, residin at Chicago, inthe county of Cook and tate 0f Illinois, have invented a certain new and useful Improvement in Windmills, of which the following is a full, clear, concise, and exact description.

My invention relates to windwills and has for its object the provision of improved means for lubricating the wind wheel shafts.

The windmill of the invention includes 4lubricating mechanism having a basin containing lubricant and formed with a sleeve' extension having an open outer end, a shaft journaled in sald extension, motion transmitting mechanism including a gear wheel upon the shaftJ and within-the basin and dipping into the lubricant contained in the bas1n,and means for transferring lubricant elevated bythe gear 4wheel to the shaft within the sleeve, there being a return passage beneath the sleeve extension and connecting the outer end thereof with the basin. The basin is lmounted to turn upon an upright axis and the sleeve extension of the basin is horizontal. The wind wheel has a hub portion surroundingthesleeve extension and Aclosed ended to guard the open end thereof against the weather. l

The invention will be more fully explained by reference to the accompanying drawings in which 1 is a sectional plan view illustratin portions of the windmill structure as suc is preferably made; Fig. 2 is a sectional view n line 2-2 of Fig. 1;

Fig. 3 is a side view of the upper portion of the windmill containing the mechanism of the invention; Fig. 4 1s a sectional vlewfon line 4-4 .of Fi 1; Fig. 5 is a sectional view on line 5-5 o Fig. 1; Fig. 6 is a sectionalview on line (36 of Fi 3; and Fig. 7 is a sectional Vview on line -7 of Fig.- 1.;

j Like parts are indicated by similar char- \acters of reference throughout the different figures.

The wind when haa 1 is provided with4 bearings 2, 2 and 3 carried by a lgear housing 4 which is made imperforate, particularly at its lower portion, so as to contain --lubricating oil illustrated at 5 in its lower portion, The shaft 1 carries pinions or small spur gear wheels 6 which are in drivin mesh engagement with larger gear g wheels 7 that are operatively connected with `right axis in any usual or suitable way and 'is a suitable load operating pitman which does not 'need to be illustrated. A washer 8 is pressed against the left. face of the left pinion 6 by a conical coil spring 9 which tends to dlstend axially of the shaft 1 to effect the application of its pressure )against the washer 8, the `baseof the spring 9j resting against the housing 4 at the right end of the bearing 2. The washer 8 is circular. at its right and left hand sides but is en larged at its upper portion 10 beyond the periphery of the adjacent pinion 6 so as to engage a lug 11 carried by the housing whereby the washer is withheld from rotation. The washer is cut away beneath the overhanging extension 10 and within the circle of its side portions so as there to constitute an entrance to an oil conducting trough 12 which terminates at its outer end in a leader 13 provided for directing the oil into an opening 14 in the bearing 2. lThe oil conveyed through the trough 12 is directed to the openin 14 by the leader 13 and finds its way directly to the shaft 1 at the opening f14 and worksendwise of the shaft in both direction, some ofthe oil that works beyond the bea ing2 to lthe left ultimately finding a return to the housing interior through the return passage 15. A spiral groove 22 promotes the passage of the lubricant through the bearing 2. It .is desirable to limit a portion of the lefthand pinion 6 to engagement with the right hand border of the trough 12 as much as possible, on which account the washer 8 has a downwardly extending projection 16 which bears against the associate pinion 6outside of the circle of the sides of the washer. v

The basin is mounted to turn upon an upformed with a horizontal sleeve extension 17 in which the wind-wheel shaft 1 is 'ournaled and'through which the shaft exten s at both ends. The bearings 2 and 2 are spaced apart between the ends of the sleeve extension to 100.

, form an annular lubricant receiving lpassage 18- from which a portion of the lubricant returns to the basin through the passage', 15, the balance of the lubricant worklng its way to the left through the bore of the bearing los 2 and thence through the outer open end ofy `this bearing and sleeve extension to -ind its way back to the basin through the passage 19 which underlies the sleeve extension proper, this passage being preferably formed n0 I extenslon from the in an enlargement of the sleeve extension and communicating with the outer open end thereof.

To guard the outer open end of the sleeve Weather, such sleeve extension is desirably extended to the left to form an overhanging annular a ron 20. The shaft 1 projects at its left han end through and beyond the sleeve extension, and is there assembled with the hub 21 of the wind wheel 22. Further to guard the open end of the sleeve extension from the weather to revent water from indin its way to the lu ricant containing basin, t e -hub 21 is formed with a portion 23 which surrounds the outer end of the'sleeve extension and projects inwardly beyond the same toward the basin. When the wind wheel is in the wind, driving rain is prevented from being wind driven into the sleeve extension and the lubricant returning passages communicating therewith. If the wind wheel is out of the wind the sides of the hub extension 23 will similarly guard the lubricant. The oil ducts that communicate with the bore of the sleeve extension are referabl so disposed and the lubricant evel in e basin is desirably such that the lubricant will not rise above the axis of the wind wheel shaft. While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without de- Karting from the s irit of my invention, but

aving thus descri d my rinvention I claim as new and desire to secure by Letters Patent the followin In a windmill, the combination with a basin mounted to turn upon an upright axis formed with a horizontal sleeve extension; of a shaft in said extension, there being space between said shaft and extension and between the ends of the extension for receiving lubricant; power transmitting mechanism including a ear wheelA upon the shaft and Within the asin and dipping intothe lubricant contained in the basin; meansv for transmitting lubricant elevated by the gearwheel to the inner end portion of the aforesaid sleeve extension, there being a return passage beneath the sleeve extension; and a wind wheel upon the outer end of the `shaft which projects beyond said sleeve extension, this Wind wheel having a hub portion surrounding the sleeve extension and closed ended to guard the outer end of the extension against the weather, said sleeve extension terminating short of the closed end of said hub portion.

In witness whereof, I hereunto subscribe my name' this 6th day of July, A. D. 1922.

DANIEL R. SCHOLES.
